Man this is your own analogy, do I really gotta explain it
If everyone is suddenly playing at the nuclear poker table, the chances of SOMEONE going all in each hand drastically increases, and if any one singular player goes bust, we ALL lose because the damn table explodes
Appeasement just kicks the can down the road (and makes things much worse in the future), it’s vital that we not make playing nuclear poker appealing by letting countries get away with shit even if they do have nukes
